In the picture shown here, blocks of the ground seem to have broken off from a main portion of the surface, and are rotated. You can tell that they are rotated because the "linea" on the rotated blocks stretches in a different direction than the linea in the rest of the picture.
Notice that for this to happen there must be a very soft layer underneath the icy block.
